Title: Soldering and packaging substrate for fine lead pitch part
Inventor: YAMAGUCHI HIROYUKI
IPC: B23K1/012
Filed: 1988-09-30
Abstract: PURPOSE:To prevent development of a bridge by jetting hot blast through a nozzle, by spraying it to an aimed area, by dissolving solder for soldering, by moving this heated jet flow, and by moving excessive solder successively by use of blowing action of jet flow. CONSTITUTION:Cream solder is applied to a packaging substrate 8, and QFP (Quad Flat package) 7 is placed thereon. Hot blast is sprayed in spot through a nozzle 6 to a solder section on a pad to dissolve the solder. Hot blast to the nozzle 6 is developed by a hot blast developing device 5 and supplied through a hot blast transmission tube 4 and a nozzle holding head 1. In the meantime, movement along pad arrangement is made by a biaxial rectangular robbot 2. A lead and a pad are soldered by heated jet flow from the nozzle 6 and excessive solder which is blown successively is moved to a solder gathering pad 10 at the end of a pad line. Development of a bridge can be thereby prevented.

IPC: G02B7/28
Filed: 1989-09-22
Abstract: PURPOSE:To enable highly accurate detection of eye sight of an examinee from a cornea reflection image even when the contrast of the reflection image is low by arranging an amplification means to perform an amplification with a large gain when an output signal from a detection means is in a small range as compared with that when it is in a large range. CONSTITUTION:A projection lens 6 makes luminous flux from a light source 4 parallel to light over the surface of cornea 1 and a light receiving lens 7 forms images of a position (d) at which a cornea reflection image is generated near the cornea 1 and ends (a) and (b) of iris on the surface of an image sensor 9. An output signal from the image sensor 9 (401) is amplified in inversion with an inversion amplification circuit 402, a dark signal voltage V1 is subtracted with a differential amplification circuit 406 from the output signal and a true signal voltage portion is supplied to a non-linear amplification circuit 452 comprising resistor 407-409, diodes 410 and 411 and an operational amplifier 412. Then, the voltage portion is amplified in a large gain in a small output signal voltage range V1-V2 and it is amplified in a small in a large output signal voltage range V2-V3. Thus, a spot position of the cornea reflection image of an eye ball and a center position of a pupil can be detected at a high accuracy.

Title: Digital sound recording and reproducing device
Inventor: KANIWA KOUJI
IPC: G11B15/087
Filed: 1986-10-20
Abstract: PURPOSE:To attain rapid and automatic program searching by recording a specific bit string as an index signal on a recording track in the vicinity of a PCM data area and reproducing it to execute the program searching of a PCM data area. CONSTITUTION:A specific bit string, e.g. a 0-bit string or 1-bit string continued over one data frame or more of PCM sound data, consisting of the combination of binary codes not appearing in the PCM data is recorded in the vicinity of a time axis compressed PCM sound data recording area (PCM data area) as an index signal of a music program recorded in the area. The index signal is reproduced and discriminated at a state sharply increasing a tape traveling speed as compared to the normal reproducing time. Since the number of musical programs can be counted by counting up the number of the discriminated index signals, program searching can be attained by traveling the tape up to a position where a required musical program is recorded.

Abstract: PURPOSE:To cause areas to return surely to normal always in the order from an area of higher importance to that of lower importance, by closing a breaker by priority to a power flow with a larger estimated value flowing through said breaker to be operated in a target system. CONSTITUTION:Power flows respectively flowing through each of transmission lines LN1, LN2, LN3 and a transformer TR1 are designated as P1-P4, and said power flows P1, P2, P3, and P4 are supposed to be 200MW, -50MW and 100MW, respectively. First, the estimated values of three breakers to be operated are obtained by the equation on the basis of power flow values in a target system. The estimated value W3 of a breaker CB3 is W3=50. In like manner, the estimated values W4 and W5 of breakers CB4 and CB5 are W4=150 and W5=100, respectively. The priority order of operation is given in the order from a larger estimated value to a smaller one. That is, said breakers are operated in the order of CB4, CB5, and CB3. Therefore, when the breaker CB4 is first closed, areas return to normal in the order from the most important area with a large power flow value.
